摘要：
A method of increasing the amount of diphenylcarbonate produced per amount of catalyst consumed in a phenol carbonylation process is described. Phenolic carbonylation produces water as a reaction product which reduces the turnover number (TON) of the catalyst. A mixture of a phenolic precursor, a base containing catalyst and co-catalyst components and at least one chemical additive comprising a halide or hydroxide of alkali metal or alkaline earth metal when carbonylated together under specific conditions increases the turnover number (TON) and water resistivity of a palladium catalyst. The metal halide likely makes the catalyst less susceptible to degradation by water hence increasing the reaction yield per weight of catalyst consumed.
摘要（中）：
描述了在苯酚羰基化方法中增加每消耗的催化剂生产的碳酸二苯酯的量的方法。 酚醛羰基化产生水作为反应产物，其降低催化剂的周转数（TON）。 当在特定条件下一起羰基化时，酚前体，含碱催化剂和助催化剂组分的混合物和至少一种包含碱金属或碱土金属的卤化物或氢氧化物的化学添加剂增加了周转数（TON）和水电阻率 的钯催化剂。 金属卤化物可能使得催化剂不易受水的降解，因此增加每消耗催化剂重量的反应产率。
